Abstract
The charge-transfer (CT) complexes of Schiff bases 2a-e derived from S-methyldithiocarbazate and tetracyanoethylene (TCNE) have been studied spectrophotometrically. S-methyldithiocarbazate 1 reacted with TCNE to yield 3-amino-4,5-dicyano-6-S-methyl-pyridazine 12 and 4,5-diamino-1,8-di-S-meth-ylpyridazino[4,5-d]pyridazine 13 via CT-complexes, whereas 2a-e reacted with TCNE to afford 3-aryl-4-amino-5-cyano-6-S-methylpyridazines 22 and 3-aryl-5-S-methyl-1,2,4-thiadizaoles 16.Keywords
